INSTALLATION GUIDE
EON Lithium batteries are fully compatible with Phocos inverters that have Modbus (RS485) communication capability. The setup guide will assist the installer with the correct configuration and setup of the inverter and battery.
Note: these settings only apply to one battery. For multiple batteries, please follow the instructions in the manual as well as the best practices for paralleling batteries.
The comms cable will be plugged in at the RS485 port on the battery (not the cascading or parallel ports) to the Li-ION port on the inverter (Below the display).

The recommended shutdown % is 20% as it will prolong the battery life and deliver optimal performance.
-
On the inverter settings menu go to setting 5 for Battery Type setting.
-
Select ‘’LIb’’

Power cables
-
Check the rating of the inverter and the battery pack that will be working together. Make sure that the correct gauge cable is used and the correct fuse protection.
-
If the power rating of the battery is lower than the inverter, then make sure the maximum discharge current is set to conform to the battery power rating.
Example:
-
Inverter = 8kW (Max power is 8kW or 160A DC)
-
Battery = 5kWh (Max power is 5kW or 100A DC)
-
Set the maximum discharge current to 100A in the battery settings.
-
For batteries connected in parallel, please see the best practices guide.

Parallel or Multiple battery Installation – EON Lithium Dip switch settings
If you are using one battery, then set the DIP switches as the master or Battery 1. If you have multiple batteries in parallel, then follow the table below to set each battery accordingly. Also make sure to connect the supplied comms cable between the battery RS485 parallel ports (7 in following figure):
